When you think of a cappella, do you think of just cheesy barbershop? Think again. Give a listen to Una Aura Amorosa, sung by the Swingle Singers.
[and for those outside the U.S. who cannot access the lala clip above, you can view a live performance of this song from the same group here on YouTube]
If you don’t agree that there is beauty here, you need your head examined ;-).
The Swingle Singers actually have quite a varied (and often amusing) repetoire. The song referenced above is from their 2CD combo: Bach Hits Back ~ A cappella Amadeus.
